Boiled pass. side battery last Wednesday when hauling wife's horse to be reshod. Replaced batteries and volt meter showed over charging and the rail pressure gauge was bouncing all over the place While driving home. Truck even surged when pulling some hills. Finally was able to check things out this evening, cleaned all connections and grounds. Checked connection on FCA wiggled it a little bit to make sure good connection. Started truck up and the rail pressure was pegged and truck was idling rough. Shut truck off and wiggled wires on FCA and started truck and all was fine. Could FCA be bad or connection be bad. Wire from alternator to battery looks bad, is it a special wire or what size is wire to make and replace.
